ABSTRACT:
An injector including an electrically operated valve connected to a pressurized liquid supply source, is provided in a fuel supply system of an internal combustion engine, to inject fuel from a fuel tank supplied under pressure by a fuel pump. The injector has a housing having a conduit to receive fuel and a movable core (member) disposed in the conduit. The movable core has a valve. When a solenoid is energized, the movable core moves against the flow of fuel to open the valve, while allowing fuel to flow between a conduit surface and the movable member to as far as the valve. Grooves are formed on at least one of the conduit surface and a surface of the movable core, preferably on the conduit surface, in a direction parallel to that in which the movable member moves. These grooves act as fluid passages, reducing the fluid resistance encountered by the movable core and enhancing the valve stroke response. Moreover, the conduit surface and the surface of the movable core in contact therewith are subject to high-hard coating treatment to improve durability.
